Rubber Wires And Cables Are Widely Used

The main characteristics of rubber power cords are: pure conductor metal, no insulation, no sheath, such as steel core aluminum stranded wire, copper aluminum bus bar, electric locomotive lines, etc.; the processing technology is mainly pressure processing, such as smelting, rolling, drawing , Stranding/tight twisting, etc. ; Products are mainly used in suburbs, rural areas, user main lines, switch cabinets, etc.
The main characteristics of rubber power cords are: Extrusion (winding) of the insulation layer outside the conductors, such as overhead insulated cables, or multi-core stranded wires (corresponding to the phase wires, neutral wires, and ground wires of the power system), such as the above overhead insulated cables , Or add a sheath layer, such as plastic/rubber sheathed wire and cable. The main processing techniques include drawing, stranding, insulation extrusion (winding), wiring, armoring, sheath extrusion, etc. There are certain differences in the combination of different processes for different products. The products are mainly used for the transmission of strong electric energy in transmission, distribution, power transmission and transformation and power supply lines, with large current (tens of thousands of a to thousands of a) and high voltage (220 V to 500 kV and above).
The main characteristics of rubber power cord manufacturers are: complete specifications, wide application range, and more voltages of 1kV and below. Facing special occasions, new products are continuously derived, such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free/low-smoke halogen-free cables, termite-proof, rat-proof cables, oil-resistant/low-temperature/wear-resistant cables, medical/agricultural/mining Cables, thin-walled wires, etc.
At the construction site, rubber wires and cables should be laid underground or overhead. It is strictly prohibited to lay on the ground to avoid mechanical damage and medium corrosion. Overhead lines must use insulated wires, and insulated wires must be erected on special poles. It is strictly forbidden to erect on trees, scaffolding and other facilities. The direction of buried cables shall be marked with direction. The cable type should be selected according to the laying method and environmental conditions. For buried laying, armored cables should be used. When armored cables are selected, they should be waterproof and anticorrosive. Unarmored cables should be used for overhead laying.
